K 5742 A B S T R A C T A PROCESS FOR THE PREPARATION OF COMPOSITE CRYSTALLINE ALUMINIUM SILICATES AND THEIR USE AS CATALYST (CARRIER) Process for the preparation of a composite crystalline aluminium silicate by maintaining an aqueous alkaline starting mixture comprising one or more silicon compounds, one or more aluminium compounds, one or more compounds of metals from Group la of the Periodic Table of the Elements (MX) and organic nitrogen compounds at an elevated temperature until composite crystalline aluminium silicate has formed and subsequently separating crystalline silicate from the mother liquor, wherein the various compounds are present in the starting mixture in defined molar ratios. The composite crystalline silicates can be used as catalyst (carrier) for dewaxing hydrocarbon oils, and for separating hydrocarbons. CCRH04
